Kourtney Kardashian still has one week left before she turns 40, but her family is already celebrating the milestone birthday!

In a sweet (and hilarious) video released Thursday by E! News, Kourtney’s sisters Kim Kardashian and Khloé Kardashian, ex-boyfriend Scott Disick, and two eldest children, Mason and Penelope, sent well wishes to the Keeping Up with the Kardashians star.

To kick off the video, Kim, 38, said with a laugh, “Good Lordy, you’re turning 40, Kourtney.”

“I can’t even believe this is how old you are,” the Kimoji creator continued. “When I think of you and your birthday, I think of dancing drunken nights in Mexico, so I can only imagine how big we’re gonna do it up for your 40th birthday. I’m always so proud that you came before me, so I’ve always copied you and watched everything that you’ve done and followed in your footsteps. So, thank you for being the best sister, the best mentor and I love you. Happy birthday.”

Khloé, 34, was next to chime in, telling her big sister, “Happy birthday Kourt! I love you so much. You will always be the Jane to my Suzanne, the Reese’s to my Pieces, the peanut butter to my jelly.”

She continued, “I really can’t imagine my life without you. I love you so much. I think you are one of the funniest people I know when you’re actually paying attention at life. I love you, have the best time, and I hope you drink tequila until you vomit all over yourself and sleep in it, because you actually have done that a couple of times.”

Last but certainly not least, Disick — who shares sons Mason, 9, and Reign, 4, and daughter Penelope, 6, with Kourtney — praised the birthday girl as a “wonderful” mom in his loving message.

Sitting beside Mason in the clip, Disick, 35, began, “Happy birthday, Mom. Happy 40th. We wish you another happy 40 to come.”

Penelope chimed in off-camera, “She looks like a kid.”

“Keep up the good work, and you look very young, P says,” said Disick, before Penelope continued, “You look like a 1-year-old.”

Disick said, “We love you so much. We appreciate everything you do and do for us. And you are a wonderful, wonderful mom. We want to see you get older and shrink and get smaller.”

At that, Mason chimed in, “I don’t want her to get shrink!”

“Anyway, we love you very much,” said Disick. “Everything is awesome about you, mom. We love you very much. Happy 40th.”

And Mason agreed, exclaiming, “Facts!”

Last year, Kourtney’s 39th birthday festivities spanned a full three days. To kick things off, Kourtney celebrated one day early in Cleveland while visiting Khloé, who had welcomed daughter True Thompson a week prior.

“It’s my birthday tomorrow! Thank you @khloekardashian,” she captioned a photo of a stunning pink cake on her Instagram story.

On her actual birthday, Kourtney woke up to an adorable balloon display in her home that read “HAPPY BIRTHDAY MOM” — as well as endless bouquets of flowers. She went on to celebrate with lunch at popular Malibu restaurant Taverna Tony alongside her three children.

The kids surprised their mom with a makeshift ice cream birthday cake topped with raspberries, chocolate drizzle and a candle.

“My kids made this for me,” she captioned a video of them presenting her with the sweet treat.

A day later, Kourtney had returned to Los Angeles, where she celebrated with an intimate at-home bash surrounded by friends and family, including momager Kris Jenner and Kim and Kendall Jenner.

Kourtney’s Pop-Up Birthday! special airs Sunday at 7 p.m. ET on Sunday.
